Tech-Savvy Riders
The WHILL app adds drive modes, ride stats, and lock/unlock — and the scooter can charge your phone or tablet along the way.
Frequently Asked Questions
The Model R uses two motors and front wheels that rotate, letting it pivot in a 38.2" radius — tighter than most three-wheel scooters — while keeping four-wheel stability.
Its lithium-ion battery is approved for air travel. Remove the battery, carry it on board, and check the scooter. Airline policies vary — confirm with your carrier before you fly.

Choose among three drive modes, check device stats like distance and remaining range, and lock or unlock the scooter from your phone.
It's IPX5 water resistant, so light rain is fine. Avoid heavy rain, standing water, and pressure washing, and dry it off after wet rides.
